Application filed August 4, 1908. Serial No. 446,943.

To all whom it may concern:

Be it known that '1, JOHN F. PARKER, a

citizen of the United States, residing at Kan- 1892, granted to Hugo Cook, No. 514,670,

dated February 13, 1894, to J. P. Cleal, and 580,378 dated April 13, 1897 to Clealand Reinhard, alsothe 'machines forming the subject of my pending application Serial No. 427,380, filed April 16, 1908, and my application No. 446,400, filed August 1, 1908. It will be understood however from the descrip tion hereinafter given that many of its fea tures are not restricted to such machines but are applicable to others also.

In the drawings, for the purpose of illustration I have shown my improvements as applied to a machine substantially as described in the aforesaid patent to Uleal and Reinhard No. 580,378. a

One of the distinctive features of this invention as of the inventions covered by my pending application is a bank of keys provided for registering and indicating the nine different amounts, in cents, ending with the numeral such as 15, 25, 85, &c. It has 'been necessary in machines of the above classes to operate two keys in order to reg ister any of the above amounts while in my improvements, the same results are accomplished by the operation of one key only.

Another distinctive feature of my machines is the means for indicating the amounts so'that they are exhibited from the four sides of the register making them visible from any part of the room.

While I do not show in my drawings or describe the printing mechanism as in the above Patent No. 580,378 before referred to, it will be understood that my improvements will not interfere with the installing of this or any other printing mechanism which is adapted to registers of this class.

Another feature of my invention is a setting key or lever for indicating the initial of clerks or special transactions such as Cash, Charge, Paid out, etc. lntlnsrespect the arrangement of the mechanism is such that I after setting the key to indicate a particular transaction the machine will repeat indicating the same at each subsequent operation without again operating the lever. In this manner the salesinans time and labor are minimized for in the general run of business the majority of transactions are for cash or the same clerks initial might be used a successive number of times. A further im-' provement in this feature is in indicating these special items so that they are exhibited from the four the figures which indicate the amount of the transaction. Another feature of this setting lever is its'action on the registering mech anism, viz. throwing the. above mechanism out of operation when the lever is'set to indicate such transactions as Charge, out, etc., since these items should not'be added and yet it is essential they should be indicated and recorded. While the above lever when set to indicate such items asQash, Received on account, etc. returns the mechanism to itsnormal position so that all such transactions are registered as well as indi cated. v

The details of construction, arrangement and operation of my invention are as hereinafter described and illustrated in the accompanying drawing in which- Figure 1 is mainly a front elevation of the machine, portions of the casing being in section to show interior constructions, Fig. 2 is mainly a main View of the machine, a portion of the casing being in section, as in Fig. 1; Fig. 3 is an end view of the gearing directly connected with the crank shaft; Fig. 4 is a vertical transverse section on the line 4-4 of Fig. 1 Fig. 5 is a section showing a row of keys and a depressible member with which they are operatively connected; Fig. 6 is a vertical transverse section on the line 66 Fig. 1; Fig. 7 is a face view oi a bar for throwing the adding mechanism into and out of operation; Fig. 8 is a perspective view of the so-called department key orsctting lever; l ig. 9 is a face view of a lever which coacts with the department indicating wheel.

directly below the fifth key of each bank.

The type of cash-register to which my invention as shown is applied is fully described in the patent to Cleal and Reinhard No.

580,378, before referred to, so that i shall describe only so much of that cash-register as is necessary to an understanding of my invention, reference being had for a fullerdescription to the prior art.

The hub of the operating handle A oi the machine is loosely mounted upon a stubshaft projecting from the framework, Fig. l, and has fast upon-it a gear B, wh ch meshes with a second gear C upon a second stubshaft. The gear C meshes with a gear D,

with a gear F, fast upon arotary-sha'it The shai't G extends across the machine to four gear-toothed segments 1, Fig. i. Meshing with each segment is a gear-wheel J, by

means of which the four indicatonwheels K, Figs. 1 and 4, are geared to the respective segments. These four indicator-wheels are adapted, to expose their indicating members to View at the front of the maelune. Interposed in the shaft G at its lefthand end, Fig. 6, is a crank Q, which is connected by a pitman R with an arm S, fast upon the rockshaft H, by which means at each revolution of the operating-handle and shaft G the shaft H is thrown forward and backward a definite distance. i

As before stated, the segments 1, which are geared to the indicators in the manner befgge explained, and which also actuate the register in the manner hereinafter described, are loose upon the shaft H, and the latter is caused to impart different degrees of its movement to the indicators and register by connecting the segments 1 with and disconnecting them from it, and the next feature As in the prfpr machines of this character, a latch or ciipling dea ice isinterposed between each segment and the shaft for this purpose, and each latch cooperates with one of the sets or series of keys, mounted radially to shaft H in suitable guide-plates -U, V and yieldingly held in and returned to their outer,

Loosely mounted upon this shaft are eraser ositions by coiled springs surrounding them etween the two guide-plates and confined between the plate V and pins 1V, passed through the stems of the keys.

Formed upon one side of the lower radial supporting arm of each segment I is a guideway X, Fig. i, in which fits a sliding latch.- plate Y, pulled rearward by a spring and hearing at its rear end against t e curved forward e go of a plate A fast upon the shaft H. "lhe plate A is cut away at its upper rear corner'to form a shoulder B. d hen the shaft H is rotated forward byturning the operating-handle, the curved forward edge of the plate A. moves past the rear end of the latch-plate Y until the shoulder B clears said plate, whereupon the spring pullsthe plate 1 rearward and causes its rear end to catch over said shoulder. The result of this operation is that just at the end of the forward movement of the rock-shaft H the latter will become coupled to the segment I by means of the plates A and Y, and during its return backward movement will carry the segment with it until the plate Y is disengaged from the shoulder B of the plate A. The means for efiecting this disengagement is the following: Pivoted at C to a pendent extension of the segment- I, Fig. i, is a belleranlr plate l), and is loosely pivoted to the sliding latch-plate Y. The lower horizontal portion of the plate D extends forward beneath the front end of the guideway X, while in rear of its pivot the plate is provided with a projecting lug, between which and the under side of the guideway X is interposed a spring E. This spring acts, as does the spring Z, heretofore referred to, to press the latch-plate Y rearward, and one or the other of the springs may be dispensed with without affecting the mode of operation of the parts. Pivoted to the lower corner of the front end of the plate D is a trip F whose upper end is pressed outwardly by a spring G, interposed between it and the end of the plate D. The lower rear end of the trip bears against the under side of the plate D and limits the outward movement of its upper end under the influence of the spring G, while said upper endof the trip is free to yield inwardly to pressure which will overcome the resistance of the spring G. Whenever any one of the keys is pressed inward to its limit of movement, its inner end will be projected into the path of traveler the upper end of the trip F", so that when, during the backward, movement of the segment with the rock-shaft, the trip strikes the end of such key it will be arrested thereby and its pressure against the key-will rock the bellcrank plate D upon its pivot C, and thereby throw the latch-plate Y forward and disengage its rear end from the shoulder B of the plate A, thus uncoupling the rock-shaft and segment permitting the latter to come to rest. at the point determined by the particular key which has been pressed in, while the shaft-and plate A move on backward to normal position. The inner guide-plate V of each set of keys has secured to or formed .unon it a flange provided with notches H a ong its curved inner edge," and the front end of the latch-plate Y is shaped to fit these notches when thrown forward to uncouple the segment from the rock-shaft in the manner above described.

Formed integral with the lower rearend of each plate A or otherwise made fast upon the shaft H is an arm I and fixed to the segment 1 is a stop pin 1 in the same vertical plane. The distance between the upper side of the rear end of this arm and the stop-pin of" the segment is such that the arm I will contact with the pin of the segment just as the shoulder B of the plate A clears the rear end of the latch-plate Y, so that as soon as said latch-plate has been moved rearward by the springs the segment will be positively mowed forward by the rock-shaft. By this means during the first half of each operation of the machine all of the segments which have been operated atthe preceding operation will be carried forward to initial position and the indicator-w'heels caused to present their ciphers at the indicating-points.

For the purpose of holding any key in its inner position after it has been pressed in the keys are provided with notches, which cooperate with lugs upon a detent-plate J,

supported by radial arms upon the rockshaft H, there being one of these plates for each row of keys, constructed and arranged to cooperate therewith. Mounted. beside each of the plates A is a sliding latch-plate R, supported at its rear end upon the shaft H and at its front end upon a screw S, entering the framework, and pulled rearward by a spring T. Each oi these latch-plates R cooperates with the lower end of one of the detent- )lates J, the latter normally engaging a shou der upon the upper edge of the front end of the plate R, as seen in Fig. 4, to hold the latter from rearward movement under the influence of its spring T until the detentlate is lifted by pressing in some one of the reys. Each plate R has secured upon its side adjacent the plate A and segment an upwardly-oxtemling plate U", adapted to cooperate with a stud V upon the side of the latch-plate Y.

lifted and its lower end d iscngaged from the shoulder of the sliding plate R, thelatter will be pulled rearward by its spring T and the plate U be carried away from the stub V so that the latch-plate '1 is then free to move rearward, as soon as the shoulder B of the platen has been carried belowits rear end. At the resetting of the segments, during the first half of the opera-t ion. or the 1na- Vr'hen any key in the series is pressed in, and the detent-plate J thereby chine, the studs V upon. the latch-plate Y will contact with the upper'forward corners of the plates U thus before the segments have reached their forward limit of movement, and the latches will be forced forward as the studs ride over said plates and the rear ends of the latches be thereby disengaged from the shoulders B of the plates A. 'lhis is the operation assuming that no key in any row has been pressed in, but if a key in any given row has been pressed in, then the sliding plate R corresponding to such row will have been pulled rearward by its spring 'l" and its plate U have been carried so far rearward that it will not serve to disengage the latch Y from the shoulder B at the end of the forward movement o1 the parts, and the segment will therefore remain coupled to the rock-shalt and be carried backward by it.

Near the end of each operation of the machine all the plates R, are thrown forward to normal position, permitting the detent plates J to drop behind the shoulder upon the plates R and release the operated keys, by cams or other projections 1'' last upon the rock shaft, which projections contact with studs Z upon the plates R and force lhem forward.

From the foregoing description it will be understood that when a key in any set pressed in and the oierating handle then given a complete rei-olution the segment 1 corresponding to such oi keys will be coupled to the rock-shaft H and be carried backward with said shaft a distance proportionate to the position and value of the operated key, and that such backward movement of the segment will turn the corresponding indicator wheels to expose to view at the front of the machine llKllOttlDg-lllllDbCl'S ropresenting the value of such key. Such backward movement of the "egmeul will also be transmitted to the registering mechanism to add the value of the operated key thereon, and that mechanism and the means for trans niitting the movements of the segments to it, may be next described, reference being had more particularly to Figs. 4 and 6.

The registering-wheels are mounted upon a rotary shaft B extending across the machine in front of the shaft E and journaled at its opposite ends in the framework of the machine. There are in this instance seven registering wheels mounted upon the" shaft B", of which the right hand one adapted to register units of cents and cooperates with the right hand set of keys and associated mechanism, the second one registers lens of cents and cooperates with the second set of keys, etc. Four wheels are driven by the res)ective segments 1, with which they are tln'onn into and out of gear [or that purpose.

Loosely mounted upon the shaft B (or upon the extended hubs of the registering wheels) are four pinions D one for each of 1 Cleal No. 589,378, before referred to.

four pinions arepermanently geared, 'directly or indirectly, to the respective gears J,

which mesh with the respective segments I as heretofore described. The pinio'ns D are thutturned forward and-backward by the movements of the segments 1. Each pinion D has fast uponits side a smaller pinion F which is operatively connected'ivith' Wheels through the medium of smaller pinions H mounted upon arms A secured fast upon, and projecting upwardly from, a rock shaft J which extends across the machine below and'in front of the train of wheels on shaft B One of the pinions H is located adjacent to each of the pinions Diimmediately in front of a pinion F and meshes with the latter when thrown rearward by rocking shaft J It is unnecessary to describe this mechanism fllI'bll6I since it is merely adjunctive to this machine, but, for details,

reference may be made to the patent pf t suffices to understand that, so long as the pinions H remain in their forward, position, shovvn in Fig. 4, the pinions D wfll remain disenga edfrom their respective registering Whe'es and be idly turned by the gears J and segments, but when shaft J is rocked andthe pinions H are thrown rear d into mesh with the pinions W, the pinicnsD Will be connectec "with the pinions re istering-Wheels, so that the latter will be pcs ely geared to the se ments 1 and the movements of said segments be transmitted to them The rock-shaft J has secured to it a depending arm L Fig. 6, to which is pivoted the front end of an armld, Whose rear end is slotted and embraces the rotary shaft G, heretofore described. A cam fast upon the shaft G, cooperates with a pin P u on the side of the arm M to throw said arm forward and backward at each 0 eration of the machine and revolution of t e shaft G, and the adjustment of the parts is snch that the arm M Will be thrown forwa Pat thebeginning of the backward movement of the rock-shaft H to carry the pinions H into mesh with the pinions F G so that the backward move ments of any of the segmental, will be transmitted to the corresponding registering Wheels. plated its backward movement, but after the segments I have been given their complete backwardmovements, the cam O -will draw the arm l 2 rearward again and disengage the pinions H from the pinions W, G and they will remainvso disengaged during the fora ard movement of the rock-shaft and forward resetting movement of the segments I at the next operation of the machine in this manner and by this means the registers ing-Rr heels are thrown into gear nith the segments at the beginningof the registering movements of the latter-and ontot gear/with Before the rock-shaft H has com-;

eraser them at the end of their registering movements, "so that during the time the-Wheels are to=be actuated by the segments they'are positively geared to them, While during the time they are not to be actuated by the segmoms they are wholly disconnected from them. For the purpose of locking the pinions H from turning whilein their forward positions and holding them in proper positionto mesh with the pinions F D when thrown rearward there are provided a series of fixed locking arms or dogs Q fast'upon a fixed shaft R and adapted to engage the pinions i when the latter are thrown forward and lock the same, Fig. 4.

The transfers between the registeringvvheels are effected by substantially the same devices as those shown and described ,in Patent No. 464,294,11eretof0re referred to, and need not be shown and described in this-case. 4

i trill now describe the features of the machine. which embody my invention, and, I for the purpose of more clearly distinguishing them, the parts concerned will be indicated by numerals.

extension 2 which is in the form of a smaller segment provided With teeth for operating gearing 3 by which vertical reciprocation is imparted to slidable racks 4. The latter, asshown in Figs, 10 and 11, are provided with lateral grooves which receive vertical'fi-Xed, guides 5, the same being attached to a horizontal portion 6 of the frame of the machine. Horizontal bars 7 (see Fig. 12) are rigidly connected -with the several rack bars, the attachment being such as described in my aforesaid application Serial N 0. 446,400. That is to say, the inner horizontal bar 7 is attached directly to the back of the left hand rack, but the three other racks 4 are provided with arms 8, which are rigidly attached thereto at their lower ends, and arranged parallel to, and spaced from, the bodies of the racks in order to accommodate the horizontal bars attached to other racks. Thus space is provided between the arms 8 and the bodies of the racks for vertical mov'ement of the horizontal bars 7 as required for operating certain indicators, as hereinafter described. As shown in Fig. 12, it will be scent-hatthe horizontal bars '7 are arranged parallel and bent at an obtuse angle on the right, and an acute angle on the left in order to brin their end portions-in the position required to provide for attachment and proper locatior of flexible indicatin strips 9. These, as s awn in'Figs Z, 4 an 6, eX- t end upward and slide in grooved guides 10 i'fhich are bars arranged ara'llel and curved from the vertical to the orizontal, as indicated in Fig. 4. The strips 9 bear numerals .90 As shown in Fi 4, each toothed segment I is provided wit an from O to 9, and are made of some duly flexihis material, such, forinstance, as sheet' to be shifted vertically in the slot 15 in the in the lower, than in the upper, portion. In

brass or sheet steel, so that when forced up- 1 ward by elevation of the racks, 4, they will 1 slide in the grooved guides 10 and conform to the curve of the latter. It is apparent that by such curve and the flexibility of the strips 9, I avoid an objectionable vertical extension of the dome or upper portion of the casing of the machine, which would i otherwise be necessary in order to accommodate the strips in their vertical adjustment. Figs. 1 and 4 show strips 9 arranged at the back of the machine, which is provided with slots 11 through which numbers etc. on the strips may be seen when the same are properly adjusted. Figs. 1, 2, and. 6, on the other hand, show the arrangement of strips .1 at the ends of the machine, for indicating numerals through slots 12 in the casing. Those strips which are attached to the bent ends of the horizontal bars 7, as shown in Fig. 12, are the same as appear at the ends of the casing in Figs. 1, 2, and 6,- andthose which are attached to the middle portions of the said bars 7, as shown in Fig. 12, are the same as appear at the back of the I112: chine in Figs. 1, 2- and 4. Inasmuch as the flexible strips 9, heretofore ref rred to, do not extend into the curved portion of the guides more than about half their length, they are preferably made somewhat thicker the dome of the machine, I arrange a horizontal wheel 13, the same bearing the words Cash, -Charge, Paid out, and No sale, arranged on tour divisions or. sections of its periphery and which will be seen through the slots, when the wheel is properly adjusted. The vertical pendent axis 14 of said wheel has a pulley 15 attached to enable it to be operated by means of a cord or wire 16 which is suitably connected with a lever for that purpose. So far as described, the construction, arrangement and operation of this wheel are the same as described in my aforesaid application Serial No. 446,490.

As shown in Fig. 6, the cord or wire 16 is 1 attached to the rear arm 17 of a lever 17 which is journaled on the shaft 1-1. This lever is shown detached in Fig. 9. It is pro vided with a sliding latch late Y in the same manner'as the other guide-ways X forming attachments of toothed segments 1, as shown in Fig. 4. In other words, this particular lever 17 is not provided with a toothed segment, but, instead, serves as the means for o crating, the indicating wheel 13 throng 1 cord 16. As shown in Figs. 6 and 9, it is provided like the segmentswith a pivoted attachment comprising a plate having the pivoted trip F which is adapted for contact with a key. In this instance instead of a depressible key, 1 emplby a pivoted lever 1 key 14, see Figs. 1, 6, 8, the same being mounted loosely on the shaft H and adapted dication through the slots of the dome.

front of the casing, see Fig. 1. One edge of i such slot is provided with notches arranged opposite the words Caslfi, -Charge, and Faid ut, and thel ever 14 is provided with a spring-catch for engaging said notches, so that when adjusted to one pos tion or the 1 other, it will be held in place.

The lever has a lateral projection or shoulder 14 which is adapted for contact with the pivoted tri F in the same manner as are the inner end; of the dollar keys T of the'leit hand bank. As

has been before described, when the shaft G is rotated in the direction of the arrow Fig. 6, the notched segment plate A is carried downward in the direction of the arrow, and when its notch B. has passedthe inner end of the latch plate Y, the latter is retracted or pushed inward by aid of the spring E or by a.

supplemental spring, not shown, so that it passes out of engagementv withv the notches oithe curved guide plate V and its inner end 1 being engaged with the notch B of the late A the lever 17 will be carried along wit the said plate and thus the wheel 13 will be rotated to a position to give the proper iii- 13 is obvious that this adjustment and position of the wheel 13 will correspond to the adjustment of the lever 14in the notches indicated by Cash Ghar'ge and Paid out. It will be understood that this lever '14 which, owing to its function, may be further in dicated as the department key whatever its adjustment, the nose or shoulder 14 of the same will always be in the path of the pivoted trip F, so that the nature ofthe last transaction, such as Cash for example, will be repeated at each operation of the machine, or until the lever shall have been moved to another notch. I provide this department lever 14 with an attachment for the purpose of throwing into and out of operation the adding mechanism (not shown) so that the machine when operated will not add when the key is moved from the lowest or Cash position shown in Figs. 1 and 6. In other words, the adding mechanism is always thrown out of action when the lever key 14 is adjusted opposite the words Charge or Paid out for an obvious reason. The attachment referred to is a bar 1-8 see Figs. 6 and 8, the same being ivoted to the lever 14 at a point intermediate its shoulder 14 and its fulcrum. The outer or free end ofthis bar 18 has a swell or cam projection 18 on its outer side and is adapted to slide in a guide 19 provided at the outer end of the slidable arm M see Figs. 6 and 7. The said end of the arm M is provided with a lengthwise slot 20 which receives the wrist pin of the crank L that is fixed on the rock shaft J which controls the position'oi the pinion H see Fig. 4, or in other words, serves to throw the adding mechanism into and out of action. When the bar 18 is ad s we pressed and registration will ment.

keys 21 inthethird bank be depressed,its arm I of the other two notches, that is to say, opposite Charge or Paid out, the said cam 13* will be carried beyond the guide .19 and thus the narrower portion of the bar 18 will beinterposed between the guide and the wrist pin of the crank, so that when the arm M is pushed outward by cam of shaft G, crank L will not be moved, and hence the shaft J will not berocked and the adding mechanism will consequently not be operated In Figs. 13 to 17, 1 show the arrangement of the three sets of keys which embody my improvement in this part of the machine. As shown in Fig. l, the bank of keys on the right indicates unitsoicents, the next bank tens-ohcents, and the third bank indicates cents which are multiples of 5 and end with the numeral 5. If it be desired to register any number of cents from-1 to 9 inclusive,

the appropriate key in the ri ht bank is dee effected accordinglv. Y The same result will ensue if any he in the second bank be depressed or'in 0tor words, by depression of any key in the second bank, any number of teris-of-cents up to 90 may be registered. desired to register any number of cents which is a multiple of 5 and between'15 and 95, i am able to effect this result by thedepression of a single key, whereas, in cash registers of this class and the particular one upon which this invention is an improvement, it is necessary to operate two keys to eifectthe same result. third bank, see Fig. 13, are adapted to slide in guides, and their inner ends work in guideways but do not extend into engagementwith any other parts. In other words, the function of these keys is solely to operate on or perform the functions of other keys as w' l soon be a parent. Each of these keys is provided wit a lateral arm 21 which is adapted for contact with the. curved edge of a sector shaped plate 22, see Figs. 4, 5, l3, 16, 17, the

same being provided with a lengthwise slot that receives a guide screw 23 audits inner end being forked to embrace the shaft H which serves as a guide in its radial adjust- It is apparent that if any one of the 21 a will similarly depress the sector 22. The sector 22 15 provided with a lateral arm 24 whlch'ezitendsmto contact with a lug or shoulder 25 formed on the shank 26 of the As i If, however, it be The keys 21 in the eraser fifth key 26in the right handbank or units of 6-5 cents column. The arm 21 of the keys 21 also bears upon the lug 27 formed on the shank 28 of each key 28 in the second or tens of cents bank. It will now be seen that if any key 21 of the third bank, say that which is numbered 55, see Figs. 13, and 14, be depressed as indicated by full lines Fig. 13, the shank 28? of the adjacent key in the tens of cents bank, in this instance the key marked 50, wiil'be depressed through its engagement with the arm 21 a of the key 21, and also that the shank 26 of the key 26 which is the filth in the row of the sets of units-ofcents bank will be similarly depressed and thus fifty-five cents will be indicated and registered through the subsequent o eration of the machine. in other words, t rough depression of any key 21, in the third bank,. any number of cents which is a multiple of 5 and ends with 5 may be registered; thus it is' not necessary to operate two keys for this purpose as heretofore. As has been before intimated, the arm 240i sector plate 22 is oper'atively connected with but one key, to wit, the fifth in the units of cents bank, also that each of the keys 21 in the third bank is provided with a lateral arm 21 as shown and has been already described, so that it may act upon the adjacent key in the tens-of-- cents bank and depress the same. It will be seen, therefore, that the keysin the third bank have no direct function in respect to registration, but are employed solely to act upon other keys which eii ect registration, as described. In order that the heads or larger. portions of the keys 26 and 28 in the unitsi cents and tens-oi-cents bank may remain immovable when the key 21 in the third bank is depressed, as already described and shown in Fig. 13, 1 construct the nine keys 28 in the tensof-cerits bank and the five cent or iifthkey in the units-of-cents bank in two parts, Fi s. 13 and 15, the outer portion being tubu er and the inner portion 26* and 28 being provided with a reduced portion or tenon adapted to slide therein. A spiral spring29 isinterposed by the outer and inher-portion of each of these keys.- Astronger spiral spring 30 encircles the shank 26 and 28 of each of the keys, and serves normally to elevate theshank and support it in normal position, which is indicated in Figs. 15 and 17. Each of the outer tubular portion of the keys 26, 28, are provided with lateral pins 3-1, to prevent them being projected too far through the casing, which would result from the action of the s ring 29.

in Fig. 17 the snanks 26 and 28 of keys 26, 28 respectively,.are shown supported by springs 30 in contact with the outer ortubular portion. W hen -these shanks are depressed, asindicated inFi 13, the springs 30 are aione'compressed, t e springs 29 ex-v eraser tending correspondingly. It is, however, desirable that the operator of the machine shall know with certaint that when the head ofa key in either of t e first two banks is depressed, its inner end shall have reached, and shall be retained, by engagement with the sector J and thus he could not know if the head were allowed to immediately resume its normal extended position shown in Figs. 13 and 17. I, therefore, provide means for locking together the two parts ofeach of these keys when depressed. To this end, a spring catch 32 is attached to the side of each of the shanks 26, 28*, and projects upward and is adapted to engage a notch 33 formed on the lower end of the tubular plortion of the key, see especially Fig. 15.' W en a key in either of the first two banks is depressed manually, it will be pushed in far enough to carry the catch 32 into the fixed guide 34 whereby the catch will be forced into engagement with the notch 33 and thus hold the outer portion 26 or 28 of the key in the depressed position, in other words, the two sections or portions of the key will be held in contact as indicated in Fig. 26 until the inner end or shank of the key shall be released in the further operation of the machine.

I claim:
